Leopard gecko questions?

I am considering getting a leopard gecko and want to make sure from the start i am caring for it properly

I was going to say what i have learned and would like someone to review it and correct and add things necessary

Habitat

A 10 to 20 gallon tank will suit them, i will prolly get a 15

I will use reptile carpet

I will hav 3 hides one on each side and one in the middle

On one side i will hav a heat lamp that produces around 90 degrees(will turn off at night)

One the other side under the tank and under a hide i will hav a heat pad set for around 80 all the time

I will also hav a shallow water bowl on the cool side of the tank

Also a small calcium bowl

And maybe some other decoration

Anything else?...

Feeding

Will feed meal worms every other day

How much though? What should i know about this? Please educate me

I will coat them in calcium powder before though, i know that

Maybe feed a cricket here and there to watch :)

Cleaning

Will clean out waste as produced

How often should i take the carpet out and clean it? Once a week?

How often should i empty the whole tank and clean the glass?

Will change water every other day or sooner if needed

Handling

Will let in tank for a few days then begin to put my hand in for a few days then eventually hold when calmed down

Any tips on this matter?

I dont want it to hate me!

What else do i need to know? Please im all ears

Thank you for your time
